Uneven cooling will also affect the quality of the weld. In fact, when using graphite products when used as the introduction of the feed shoe factory in Shandong Aluminum tee, contact with the graphite side profiles are also prone to oxidation phenomena have a black belt in Shandong Aluminum tee suppliers, especially in the hot summer months. This is due to the characteristics of graphite to make the profile local temperature rise tee manufacturer specializing in the production of aluminum, thus speeding up the surface weld grow grains. But the cooling capacity of the device enough, you can avoid this phenomenon is known as ultra high strength 7075 aluminum alloy, the yield strength of the alloy close to tensile strength, yield ratio high aluminum tee, also high strength, but the ductility and high temperature intensity than the end to do a normal temperature, load-bearing structural components below 120 ℃ to use, easy processing alloy, has good corrosion resistance and high toughness. The alloy is widely used in aviation and aerospace, and became one of this area's most important structural materials. Physical properties and mechanical properties of tensile strength: 524Mpa 0.2% yield strength 455Mpa Elongation: 11% elastic modulus: E / Gpa: 71 Edit this paragraph 7075 Product Features 1. High-strength aluminum tubes heat treatable alloy. 2. Good mechanical properties. 3. Use good. The ease of processing, good wear resistance. 5. corrosion resistance, good oxidation resistance.
